Link reliability is a significant issue for free space optical links. Inclement weather, such as fog, can seriously reduce the transmission of light through the atmosphere. However, this effect, for some types of fog, is wavelength-dependent. In order to improve link availability in both metro and hostile environments, mid- and far-wavelength infrared diode lasers can be of use. This paper will discuss some of the recent advances in high-power, uncooled quantum cascade lasers and their potential for use in long range and/or highly reliable free space communication links.
